4620.4510 MEASUREMENT OF AIR QUALITY CONDITIONS. Subpart 1. Measuring air quality. Owners or operators of indoor ice arenas must measure carbon monoxide and nitrogen dioxide air concentrations in each arena when internal combustion engine-powered ice maintenance equipment is used. Subp. 2.Persons who can take measurements.Measurements must be made by an individual who has received training as specified in part 4620.4450. Subp. 3. Measurements for ice resurfacing. Owners or operators must measure air concentrations at least twice per week after using an internal combustion engine-powered ice resurfacer.Measurements roust be taken: A. at board height,inside the boards, and at the centerline of the ice; B. 20 minutes after completing resurfacing unless the commissioner has granted the operator approval to measure under an alternative schedule; C. at times of maximum use of the resurfacing machine; and D. at least once on Saturday or Sunday of each week that the arena is open to the public. Subp.4. Measurements for ice edging. A. Owners or operators must measure air concentrations at least once per week after using an internal combustion engine-powered ice edger. Measurements must be taken following a time of maximum ice edger use at board height, inside the boards, and at the centerline of the ice= (1) 20 minutes after completing edging if the arena building is open to the public when edging occurs;or (2) before the public reoccupies the arena, if the arena is not open to the public when edging occurs_ B. Owners or operators may measure under an alternative schedule if the commissioner has approved one. Subp. 5. Measurement records. Owners or operators roust keep a record of measurement findings and make them available to the commissioner upon request. Subp. 6. Additional measurements. Owners or operators roust make additional measurements as detennined by the commissioner. 4620.4550 AIR QUALITY MEASURING DEVICES. Subpart 1.Device requirements.The owner or operator must demonstrate that the device and methods used to measure air quality conditions are accurate and reliable.Air quality measuring devices must be: A_ capable ofrneasuring carbon monoxide air concentrations in a range from 0 to 100 parts per million (ppM)in increments of 1 ppm; or B. capable of measuring nitrogen dioxide air concentrations in a range from 0 to 5 parts per million (ppm) in increments of 0.1 ppm_ Subp.2. Maintenance. The owner or operator,must operate, store,maintain, and calibrate the devices according to the device manufacturer's specifications. The owner or operator roust also keep maintenance and calibration records. 4620.4600 FAILURE TO MAINTAIN AIR QUALITY. Subpart 1. Corrective action necessary. The owner or operator roust take immediate corrective action when measurements of more than 20 ppm of carbon monoxide or more than 0.3 ppm.of nitrogen dioxide are made in an area of the arena building that is open to the public. Corrective action must include: A. increasing the ventilation rate immediately; and B. suspending internal combustion-powered equipment use. The owner or operator roust continue corrective action until measurements show not more than 20 ppm of carbon monoxide and not more than 0.3 ppm of nitrogen dioxide in all areas of the arena building that are open to the public. Subp. 2. Follow-up testing.The owner or operator must conduct and document the following air quality tests to confirm the effectiveness of the corrective action: A. at 20-minute intervals until measurements show not more than 20 ppm of carbon monoxide and not more than 0.3 ppm of nitrogen dioxide; Indoor ice Arena Rules
